Yes, I agree with you that corner lots are certainly very tempting, esp the huge garden area and the almost all round view! My property agent friend told me NEVER to buy corner units in JB, so typical kiasi syndrome kick in for me. But like you said, it's probably not easy to get one in a development you like.
your friend is probably right, you know. it's fairly common sense. but corner units are rarer and so should be better investment. that's what i think anyway. So, in order to balance the two arguments, i bought a NEXT TO CORNER lot. hehehe.
